DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIG. 1 and FIG. 2, a biological hazard protection body
bag (10) of the invention has double bag case structure comprising
an outer bag case (20) made of non-transparent material, and an
inner bag care (30) made of transparent material.
Said non-transparent outer bag case (20) has lift-able bag flaps
(21). After the bag flaps (21) of the non-transparent outer bag
case (20) are lifted, the transparent inner bag case (30) covered
by the outer bag case (20) may be exposed to carry out body packing
and bag sealing work as well as the air-extraction work to isolate
the body or the corpse inside the transparent inner bag case
(30)
Referring to FIG. 1 and FIG. 4, along the two sides of the
non-transparent outer bag case (20), several binding strap (22) are
provided for tightening the body or the corpse inside the bag and
as a means to conveniently move the body bag (10) during carrying
body or corpse. Moreover, by means of the binding strap (22) the
biological hazard protection body bag (10) of the invention may
also be used as a stretcher to enable a multiple purpose
application to the present invention., in case of emergency the
injured or disabled patient may lie on the non-transparent bag case
(20), and be moved away from the scene for medical treatment. In
addition, the non-transparent outer bag case (20) further provides
with two back-carrying suspenders (23) on its back side as shown in
FIG. 4, when there is short of hands, or special terrain, the
biological hazard protection body bag (10) of the invention may be
operated and carried by single manpower by way of carrying the
biological hazard protection body bag (10) on his/her back.
And, the transparent inner bag case (30) covered with the
non-transparent outer bag case (20) is the major design feature of
the invention. The inner bag case (30) has a horizontally extending
gastight sealing strip (32) adjacent its top edge and lift-able bag
flaps (31) equipped with multiple gastight strips (32) for easy and
quick sealing the bag opening of the transparent inner bag case
(30), and after those multiple gastight strips (32) of the
transparent inner bag case (30) are snapped together those multiple
gastight strips (32) will never be broken apart even when extreme
high pressure is applied on the transparent inner bag case
(30).
Referring to FIG. 1 and FIG. 4, a vacuum filtration device (40)
comprising a check valve (41) and medical grade filter screen (45)
is installed on the transparent bag case (30).
The check valve (41) is installed in such a way which valve body is
exposed on both the outer surface and the inner surface of the
transparent inner bag case (30) with the outer part of the check
valve (41) for being connected to the air suction equipment, and
when the air suction equipment applies a suction force during
suction operation the valve blade of the check valve (41) moves to
allow the air to flow from inner side to outer side of the
transparent bag case (30) passing through the air passage of the
check valve (41), however, when the air suction equipment stops
operation, the suction force disappears, and the valve blade of the
check valve (41) immediately returns to its original position to
block up the air passage of the check valve (41) that stops the air
flow between inside and outside of the transparent inner bag case
(30).
Said medical grade filter screen (45) is installed inside the
transparent bag case (30) and installed on the open end of valve
body of the check valve (41) inside the transparent bag case (30),
which has the function able to filtrate off the particle or
pathogen with size over 0.1 .mu.m and screen the air passage of the
check valve (30). Hence, when the air suction equipment exerts
suction force on the check valve (41) to extract the air from the
transparent inner bag case (30), the air inside the inner bag case
(30) will be completely filtrated by the medical grade filter
screen (45) to prevent the small particles or pathogen carried by
the air from flowing out from the inner bag case (30), and the
small particles or pathogen will adhere to the surface of the
medical grade filter screen (45) when they pass through the filter
screen (45) to prevent the pathogen to get out of the inner bag
case (30).
Then, referring to FIG. 3, after the body or the corpse is packed
in the transparent inner bag case (30), the transparent inner bag
case (30) is rapidly sealed up by using those quick snap multiple
gastight strip (32) to seal the transparent inner bag case (30) to
form a gastight sealing, and the bacteria or pathogen carried by
the body or the corpse shall be isolated inside the transparent
inner bag case (30) by the vacuum filtration device (40) during air
suction through the vacuum filtration device (40) that may pack the
body or the corpse in a nearly vacuum space inside the transparent
inner bag case (30) to effectively eliminate the possibility of
pathogen infection or dissemination, then have the transparent
inner bag case (30) be covered with the non-transparent bag case
(20), and use the binding strap (22) to tight and fix the
biological hazard protection body bag (10).
When it is required to examine or observe the body or the corpse,
the only thing we need to do is to open the biological hazard
protection body bag (10) and lift the non-transparent outer bag
case (20), to make direct observation of the isolated body or
corpse through the transparent inner bag case (30) without causing
infection or dissemination of pathogen.
Further referring to FIG. 4, the biological hazard protection body
(10) of the invention may have a water absorption sheet (24)
arranged inside the transparent inner bag case (30), and/or have a
drugs bag (25) which is provided for antiseptic agent or pills (50)
prepared beforehand to be mounted on the bag wall inside the
transparent inner bag case (30).
Before the body or the corpse is packed into the transparent inner
bag case (30), a proper amount of antiseptic agent is applied on
the water absorption sheet (24) inside the transparent inner bag
case (30), or after the body or the corpse is packed, the drugs bag
(25) may be crashed by squeeze force from outside of the bag case
to have the antiseptic agent or pills (50) to adhere to the surface
of the water absorption sheet (24). Hence, when the inside space of
the transparent inner bag case (30) is sucked to become nearly
vacuum state, the antiseptic agent or pills (50) will gradually
evaporate to pervade the inner space of the transparent inner bag
case (30) to achieve the purpose of having the surface of the body
or the corpse be sterilized for surface antisepsis.
In addition, the medical grade filter screen (45) of the vacuum
filtration device (40) of the transparent inner bag case (30) may
be further equipped with a water absorptive but air permeable
material to prevent the medical grade filter screen (45) from being
wetted by blood or antiseptic agent to ensure the effectiveness of
preventing pathogen infection or dissemination.
Alternatively, in another embodiment, the air discharge and
filtration device has no check valve.
The practical applications of the biological hazard protection body
bag (10) of the invention includes being applied for handling the
body or the corpse due to unknown cause of death whether died
outdoors or died before sent to hospital, or died during medical
treatment but due to unknown cause that result in the need of legal
autopsy to clarify the cause of death. While in these circumstances
the corpse can be kept in a nearly vacuum transparent inner bag
case (30) with gastight sealing waiting for the required autopsy
procedure, and prevent the infection or dissemination of
pathogen.
Especially, when the nation meets with grave natural disaster such
as the earthquake on September 21 in Taiwan which resulted in heavy
losses casualties or when there is burst of war that results in the
interruption of electric power supply, and causes failure of
carrying out immediate rescue, the body or the corpse may be
temporarily stored in the biological hazard protection body bag
(10) to reduce the impact on environment and the people still
alive, meanwhile by way of keeping the body or the corpse stored in
the vacuum state and applied with antiseptic agent or pills (50)
inside the transparent inner bag case (30) may effectively decrease
the speed of decay of the body or the corpse so that the relatives
may clearly identify the dead under safe protection without causing
infection of pathogen.
